my camaro doesnt have any markins whatso ever..so i got on a site for my vin check and it came out an iroc/z28.......is it an iroc or a z? it says tbi 305 so it shouldnt be an iroc......help please?

 

Even with the 5.0 305 it's still an IROC.

 

the Z28 was droped to iroc and were made only from 1982-1990. The 91 and 92 were changed to Z28

 

Z28: 82-87 and 91-92
IROC-Z28: 85-90

The 305 TBI was the base IROC engine but wasn't all that common as most were 305 TPI's. If it's an IROC for real and an 85-87 it'll have RPO B4Z, if it's and 88-90 it'll have RPO Z28.

 

its an 88....says so on the tittle (which i have right in front of me) and it checks out on the vin search.....

 

also i dont know what advantages i have over the other modle 88's....what would they be? also any detail,advice, and ANYTHING u guys think i should know would be greatly apreciated.....


peace out from ur fellow camaro enthusiest (sp)

 

The irocs had better suspension, wonder bar and could be had with TPI over the coupe in 1988

 

Advice: Look under the lid of your center console and copy down the 3-digit RPO codes. Then go to www.thirdgen.org and run every RPO on the list through their RPO decoder. That'll tell you EXACTLY what you have.



Then get subframe connectors.

 

thanx alot guys, great tips and advice...keep it comin!

 

Go to www.ThirdGen.org and read the Tech Data.

 

you may want to start modding that badboy. Although it's an IROC, it doesn't stand a chance in stock form against other IROC's equipped with TPI engines.

 

Just to let everyone know, it's 130 am here...and when he said, 'then get subframe connectors.' it hit me hard, I was cryin on the floor laughin...I don't know why....

 

ok..the major codes that i typed in varified my tbi 305, i have a 2.73 rear end and a thm 700r7 trans......

 

thm 700r4*

 

no more tips or advice? how hard would it be to swap rear ends?
